摘　　要：该文为让学生更直观地了解超声RF信号重建出B超图像的过程,首先在超声设备上完成RF数据的采集,然后在Matlab平台上对每个成像步骤的信号进行分析,完成成像过程的仿真,最后将得到的结果与超声设备上显示的图像进行对比。该实验具有较强的设计性和参与性,实验结果具有一定的开放性。实践表明,实验过程既能锻炼学生分析问题的能力,又能加深学生对专业课程的理解,激发其学习兴趣,进而改善教学效果、提高教学质量。In order to better understand intuitively the process of reconstructing B- mode images from focused ultrasound RF signal for undergraduate students,an experiment is well designed. Firstly,it makes students complete the collection of RF data on ultrasound equipment. Secondly,it completes imaging process simulation by analyzing the collected signals in each imaging module on MATLAB platform. Finally,it compares the obtained results with shown image in ultrasound equipment. This experiment allows students participating in designing with an opening result. The practical result shows that： the experiment process can not only help students increase the ability to analyze certain problem,but also deepen students＇ understanding of the curriculum,stimulate their interest in learning. Thus this experiment will achieve the purpose of improving the teaching effect and quality.
